The size of the Solar System has been scaled down to fit within the borders of Maryland, and the individual ‘planet’ caches have been spaced out accordingly. The scale is 1 Astronomical Unit (average distance between Earth and the Sun, or 93,000,000 miles) equivalent to 3.5 miles. The tour starts with The Sun cache. If you do the whole tour, mark the cache locations on a map of Maryland and see just how vast the Solar System really is. This will hopefully give you a feel for why it takes so long for spacecraft to travel from Earth to anywhere in our Solar System.
Venus is a world in hiding. Cloud-shrouded, it reveals no surface features unless one peers in using other wavelengths. Venus is an anomaly among anomalies with respect to the planets in the Solar System. This is because it rotates backwards from the rest of the planets. The why of this is still a mystery. Venus’ atmosphere is a sulphery soup, incredibly corrosive to everything. Several space probes were sent to Venus during the 1970s. Some did not survive the drop into the atmosphere. A very few made it to the surface of the planet and transmitted some information back before all but dissolving. Venus has active volcanoes that contribute to the toxicity of the atmosphere. The constant clouds reflect most of the light that the Sun casts on it, and for us, this means Venus is one of the brightest objects in the sky when it is visible to us from Earth. Only the Moon and Sun are brighter.
This microcache is in a small 4-3/4 inch long plastic tube, multi-colored swirl to represent the bright Venusian clouds (used to be a yellow tube), tucked away in a corner of Robert E. Lee Park. This micro is too small to host its own pen, so be sure to bring your own writing instrument.
This is a cache-n-dash if you park near the bridge of I-83. There is a trail that will lead you to within 30' of the cache itself. The only hard part of this trail (other than the uphill bit 
) is going over or under the fallen tree that cuts across the trail. Very easy to get to otherwise (the original location was more sporting ).
